A plurality of screws 29 or the like serve to n-t-ain the top plate 17 on the frame '80 t2 and 1-; of tho t'rznne Ht, screws 27' or the It) and in (H'tltt' to prevent removal of the" plate 17 when the latrh bar is in retaining position, I n-ovidu a pair of blocks 30 and 1H .arrarigigod in alineinent with the blocks 25 and 2t; lmrt-inlw't'ore described. The blocks 30 and M are provided with recesses 32 complemuntal to the recesses 28 hercinbefore reterm-d to. However, the blocks 30 and 31 are spaced. from the bottom of the channel 18 in the plate 17 sufficiently to permit the heads 24 of the pins 22* and 23 to engage therebetween. V

The grooms 28 and 32 being in alinement it will' be apparent that when the latch bar is moved into retaining position the heads 24 of the pins 22 and 23 will engage the blocks 30 preventing removal of the plate 17 even after the screws 29 have been ex'-' ton-ted. Dowel pins 33 are carried by the wallS 12 and 13 of the base frame 10 and are adapted to en age in complementully formed openings in t e cover plate 17.

The lock employed may be any standard type of sliding bolt lock, the cover plate 17 being provided with a secondary cover plate for disposition over the housing 16. The plate 35 is provided with a circular enlarge ment 36 serving as a keyhole guard, the key receiving member or the like projecting into the circular enlargement 36 and being designated 37. The circular enlargement 36 is adapted to project through a suitable opening in the floor 15, a cover plate 38 being provided therefor when the same is not in use.

The latch bar 20 is moved longitudinally by means of a lever 39 said lever being putotally mounted at 40 1n a recess 41 formed in an enlargement 42 cast integrally with and prqectmg upwardly from the cover plate 17. The lower end of the ,lever'is cylindrically formed as at 43 to engage in an opening44 provided in the latch .bar 20. When the cover 'plate is placed in position on the frame 10 the cylindrical portion of thelever 39 engages in the opening 44 so that oscillation of the lever will reciprocate the latch bar for purposes which will herein after appear.

The latch bar 20 is designed to restrain movement of a plurality of members embodying the control system or mechanism of the motor vehicle, namely, the clutch lever,

foot brake, gear shifting lever and the emer' gency brake, the restraining elements of which are mounted. in recesses 47', 48, 49' and, 50, arranged in pairs in the walls 12 and 13 of the base frame 10. The clutch pedal is designated 46 and is of the usual type carried by the free end of an arm 47 keyed to a rotatable shaft 48 which is connected in any desired manner with the clutch mechanism. It is intended that the latch hair should lock the clutch lever when the clutch is in the in or operative position, in other words, the position indicated in the dotted lines in Fig. 1. In automobile practice the clutch pedal is released as a.

general rule to permit engagement of the clutch element. The clutch. lal is locked or retained in position such at the clutch is connected to prevent star ng of the en glue it the gears are out of eutral and to prevent shifting of the getrs. I accomplish this by means, togctheri with th latch bar hereinbefore described, comprising an extension 4'.) having an arm 0 thereon. As best shown in Fig. 5, the arm 50 is bifurcated as at 51, the opposite side thereof being formed with a'lined hollow trunnions 51. The free end of the tulnbler is di-. ridcd into three spaced tonlgues, the cow tral tongue 52 being roller} to provide a bearing portion in alinemen with the llOl lr|\\ tru'nnions 51. The remaining tongues 51-5 :irmbent to embrace the lnillow trunnions .31, the latter forming bearings therefor. A

the block 56 the pedal 46 must be in retracted is of the same construction as that of the clutch pedal 46. being pivoted in substan- 'a tumbler 69. point, constructed substantially like the tumpin 54 extends through the trunnions and through the rolled tongue 52 to form a hearing therefor. It will 'be seen that when the arm 50 and tumbler 52 are connected in this manner that disconnection of the same is impossible even though the pin 54 were knocked out. When assembling the tumbler is reversed, connected to the trunnions 51" and then turned over to the proper p0: sition for use, whereupon the connection is made. This connection is em loyed at all parts of the mechanism as wil hereinafter appear. One side margin of the tumbler 52 is provided witha recess 55 adapted to receive a block 56 carried by the latch bar 20 when said bar is moved into the dotted po sition as indicated by the pins in Fig. 3. However, it will be seen that. in order to bring the recess 55 into position to receive postion. The clutch is held in engaging position by the block 56 which engages the recess 55 so that the clutch is locked.

The foot brake pedal is designated 57 and tially the same manner. The arm 58 of the clutch pedal'57 .is pivotally connected at 59 to a sliding tumbler 60 similar to the tumbler 52 hereinbefore described. However, this tumbler 60 is provided with ratchet teeth 61 a ong one margin thereofi to be engaged by the pivoted awl 62 maintained 1n the position shown in Fig. 2 by means of a spring 63. The tumbler 60 is slidably mounted in the pair of recesses 48 herinbefore described. When the brake pedal 57 is depressed into the brakin position and the pawl 62 engaged with t e teeth 61, said brake pedal will be restrained from returning to normal r eleased position. The pawl 62 after engaging the tumbler 60 will permit. the brake to be moved to the braking position but will not permit release of the same until the latch bar is slid to the released position. i. The emergency brake lever is of the usual construction and is designated 64,'fl1( same being pivoted for freemovement'on a rod 65 arranged parallel to the frame 0. An extension arm 66 is clamped as-at 6 to the lever 64, the lower end of said arm bein pivotally connected at 68 to the free end 0 y The tumbler 69 is, at its pivot.

20 blers 62 and 60, hereinbefore referred to u only inverted relative thereto. One margin of the tumbler 69 is provided with a pluralityof ratchet teeth 70 similar tothe teeth 61 on the tumbler 60, said teeth 70 being l adapted for engagement with a pivoted pawl 71, said pawl automatically engaging the teeth by mcans'of the spring 72. The pawls 62 and 71m. practically identical in com I striiction, and their operation is identical, I 0

the same 1s conneote the tumbler need be moved in buta singl direction. However, in the gear-shifting lock it is necessary that movernent in hot 1 directions be arrested when movement in either direction has been once started. T ierefore, a tumbler 73' having a double set 0 oppositely arranged ratchet teeth 74 and 75 along one margin thereof is provided. he tumbler 73 is operable in a pair of r cesses 50' formed in the walls 12 and 13 of the base 10. A double acting pawl 76 is arranged on the latch bar 20 to engage the teeth 74 and 75, said pawl being carried by the free end of a flat spring 77, the opposite end of the flat spring being anchored to the latch bar. The gear shitting lever is designated 78 and is of any standard make, the same being pivotally mounted on the rod 65 hereinbefore referred to. A link 79 connects the lower free end of the gear shifting lever 78 to the free end of the tumbler 73, as indicated at 80.

The pawl 76 will permit movement of the gear shifting; lever 78 into the forward or reversed position but will not permit return of the lever: until the latch bar is unlocked.

Means is also provided whereby to shut off the fuel supply when the levers described are locked, said means including any ordinary turning plug valve 81 interposed in the fuel line c nduit 82 and buying the stem 83 thereof projecting into an enlargement 84 formed on the housing 16. A pinion 85 is carried by the upper end of the stem 83 and is engageable with ratchet teeth 86 formed on the adjacent margin of the latch bar 20. Thus it will be seen that movement of the latch bar into one or the other of its two positions will either open enclose the valve as required.

It will. of course, be readily apparent that the ignition system of the motor vehicle may be provided with a main switch connected with the pinion 85, whereby the ignition circuit may be broken simultaneously with the shutting olf of the gas or fuel supply.

The operation of my improved automobile l()(l( is as follows: a

\Vhelrtlw motor vehicle is stopped the" emergency brake lever is pulled bark to the applied position in the usual manner. The clutch pedal is left in tbe ronnected position and the lever 3!) moved to slide the block on info engag'rnu'ut with the recess 5.3 in the tumbler 52 connected with said pedal. This movrnuenl ofihe latch bar 20 shuts oil' the gas or fuel supply and, if dcsired, cuts off the ignition. circuit. The pawls 62, 71 and 7dbcingparried by the latch bar are moved into position to .e,ngage the tumblers 60, (Hand 73. ,Tliefoot brake pedali may be depressed to the applied position and the pawl 62 will hold said pedal in such position. The gearshift lever may be moved to the forward or reversed position, preferably the latter, and will be retained in that position by means of the pawl '16.. The

emergency brake. lever will beheld by the ratchet ordinarily used and releasegof the same will be prevented by the pawl 71 engaging the tumbler 6!). .A fter the-latch bar has been moved to holding position, a.key is inserted in the lock carried iuthe housing 16 and the bolt of said lock is engaged with the recess 21 formed in saidlatch har .Any attempt to remove the rover-plate l'las trustrated by means of the pins 22 and :23, and

the dowel pins 33 serve to prevent any rudwise movement of, the cover plate.

All that the owner need do on starting the car is to move the locking bar 20; to locking position whereby, to lock. the clutch in connecled position and shut oil the gasolrne; This leaves the foot brake,emergent-y, braltc and gear shift levers in clear position, i do this to leave the wheels unlocked a'iuhthc car movable as may be required by city ordinances or fire regulations.

However, the protection afforded lHGUIIlplete. If any attempt is made to tow. the car away, as soon as the foot brake is up plied it locks in applied position; If the gear lever is shifted it becomes-locked in such position. If the emergency brake is applied it also locks in applied position.

If it is attempted to start. thccar under its own power the gasolene in the carburetor will soon be exhausted and the ca r will stop.

I believe that this general funrl'io rotsettime the lock such that the car is. free to be moved and in which the controls are in normal position, but as soon as any attempt is made to use them they will be locltekl againse the fact that the device of my invention is in and of itself a unit and may br ap lied to various types of control levers not the like by merely altering the ronnectio' ibetween the tumblers and said levers. lt-will also beapparent that any numbei of these tumblers may be arrangedin the-basefrnme of my invention. Of course, it not cssem tial'that all inf the control levers bejloeked, but it is preferred that this arrangemenebe bed which assures positive lockin g 'ofthe motor vehicle.

It Will also be my invention may be readily installedlonfany of the exis-itingi, types of pnsolene propelled vehicles and may be applied to other similar apparent that the: deviceot Ill) uses without material alteration of the structure. I

From the above description taken in connection with the accompanying drawings, it is thought that a clear and comprehensive understanding of the construction, operation and advantages of my improved automobile lockzmay e readily gathered, and while I have shown and described the device as embodying a specific structure, it will be understood that I reserve the right to make such changes in said structure as do not depart from the spirit and scope of the invention as claimed.
